\( \color{Black}{\Rightarrow \tan 0 = \Large {\sin 0 \over \cos0} \normalsize = {0 \over1} = 0}\)

I believe that you are mistaken. sinx/tanx is not equal to cosx.

The number '0' spoils it all.

this property is correct since tan(A)\[\tan(A) \neq 0\]

I see that all the exceptions come from the number \(0\). I like this number. You can do anything from it(prove 2 = 1) ;)

I believe that we may just conclude that \(\Large {\sin x \over \tan x} \normalsize = \cos x , x \ne 0 \)

DHASHNIBest ResponseYou've already chosen the best response.0
but this is a property right?

\( \color{Black}{\theta \ne 0 \Rightarrow {\Large {\sin \theta \over \tan \theta}} = \cos \theta}\)

That was mathematical language.

@ParthKohli Come on !( 2=1) and yes The property is correct ! for \[x \neq k \pi \] \[x \neq \pi/2\]
 one year ago

NeemoBest ResponseYou've already chosen the best response.0
sorry \[x \neq \pi/2 +k \pi\] for the second one !
